Chapter 2, Problem 24P

Summary Introduction

To determine: The molar ratio of ${\text{H}}_{\text{2}}{\text{PO}}_4^{2-}$ to ${\text{HPO}}_4^{-}$ in a solution that can produce a $\text{pH}$ of $7.0$.

Introduction:

The Henderson-Hasselbalch equation depicts the measurement of acidity as $\text{pH}$ (potential of hydrogen) in biochemical reactions. The isoelectric point and $\text{pH}$ of buffers are calculated by this reaction. The $\text{pH}$ is used to calculate the ${\text{pK}}_{\text{a}}$ of molecules. The “ionized and unionized” concentrations of chemicals are estimated with the help of this equation. The ${\text{pK}}_{\text{a}}$ is used to calculate the $\text{pH}$ of molecules.
